If the air is warm, weak, or only cools while driving, you could be low on refrigerant—or there may be a leak or worn part (compressor, condenser, evaporator). A proper diagnostic checks pressures, temperatures, and system integrity to confirm the cause.
Technicians assess vent temperature, compressor operation, pressure readings, condenser fan performance, cabin air filter condition, and look for leaks or contamination. Findings guide the next steps—recharge, repair, or deeper diagnostics.
Most inspections and recharges are completed the same day once a bay is available. If a component needs replacement, timing depends on parts availability and the scope of work.
No. Vehicle A/C systems are sealed; refrigerant loss usually indicates a leak. The system should be tested, the leak found and repaired, and then recharged to factory specifications.
Yes. Musty odours often come from microbial buildup on the evaporator or in the ducts. Service can include replacing the cabin air filter and treating the HVAC system to eliminate odours and improve air quality.
Preventive checks help catch slow leaks, weak components, or moisture/contamination before they lead to larger failures—especially before peak summer or winter defogging season.
Common causes include low refrigerant, a weak compressor, poor condenser airflow (fan issues or debris), or sensor/pressure faults. A targeted diagnostic isolates the issue.
Yes. The system dehumidifies air, which speeds up window clearing when used with heat. If the A/C isn’t functioning, winter visibility can suffer.
any newer vehicles use R1234yf with different fittings and procedures. Using the correct refrigerant and equipment is essential for performance and system safety.
Yes. Many HEVs/EVs use electrically driven compressors and specific service procedures. Trained technicians follow manufacturer guidelines to protect high-voltage components and maintain proper cooling performance.
Stay cool and keep your vehicle running efficiently with regular A/C checks.
If you are experiencing any of these problems with your air conditioning system in your vehicle, it may be time to bring it in for servicing. One of our experienced technicians will check your air conditioning temperature, check air flow from vents, and take a look at your air conditioning components.
